J C Murphy, Plate LIII

The Alhambra, Sala de las Dos Hermanas appears to have no such pattern. This pattern seems to be an inaccurately draw version of The Alhambra, Salon de Comares.

• The symmetry group of the tiling is *442 (p4m).
• All the internal angles of the constituent polygons are a multiple of 22.5°.
• Contains two squares.
• Contains five regular 8-pointed star polygons with vertex angle of 90°.
• There are 12 non-regular reflective tiles (including one kite and one dart).
• The tiling satisfies the interlace condition and has two finite interlaces and one infinite interlace with straight cross-overs.
• The tiling is edge-to-edge.
• As drawn, contains about 777 polygons.
